Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid pump, fluid catch container.
Safety Warnings: Disconnect the battery before starting work on the electrical systems and allow the engine to cool before handling any components.

2. Change Transmission Fluid

Raise the vehicle using a jack and secure it on jack stands.
Locate the transmission drain plug and position a fluid catch container underneath.
Remove the drain plug and allow the old transmission fluid to completely drain out.
Replace the drain plug and torque it to manufacturer specifications (typically 20-25 Nm).
Remove the transmission fluid fill plug and use a transmission fluid pump to refill with the correct type of transmission fluid (consult the owner's manual for specifications).
Check the fluid level using the dipstick (if equipped) or through the fill port and ensure it is within the recommended range.

3. Inspect and Replace Torque Converter (if necessary)

Remove the transmission from the vehicle by disconnecting the driveshaft, electrical connectors, and any mounting bolts.
Carefully remove the torque converter from the transmission, noting its orientation.
Inspect the torque converter for any signs of wear or damage (cracks, excessive play).
Replace the torque converter with a new, OEM or high-quality aftermarket part.
Reinstall the transmission and ensure all connections are secure.
Refill the transmission fluid and check for leaks before starting the vehicle.
